Cement screed is a fairly reliable and very common base for different types of floors. However, if you rush too hard and do not endure the full drying time of the flooring, you can hopelessly spoil any finished flooring material. Then the work will have to start over.

This material discusses how much glaze should dry and when it is possible to begin laying the finish.
What factors affect drying time
Before you begin any repairs, you should specify exactly how long it will take to complete them, as well as how many raw materials or materials you need. This will allow you to set the time accurately and meet deadlines, you get a good result. The cement base for the floor requires the most time to fully cure.
The longevity of floor screed drying can be affected by various factors, including:
The microclimate in the room where the repairs are made, that is, the humidity and air temperature levels; number of fillings and thickness of concrete liner; concrete solution component composition; how conscientiously made the base waterproofing.
It is important not to confuse the time of setting and drying the screed. The initial placement of the cement mortar occurs in about one day. After that, you can’t be afraid to leave marks and bumps on the fresh floor. However, there is still a lot of fluid on this floor, which will gradually increase through the micropores. If prematurely covered with any flooring, it will quickly break down. Therefore, it is important to know how much screed will need to dry to be laid on a clean floor.
As a rule, the average time required for complete screed drying is 28 days, if optimal conditions are created.
Humidity level
The most acceptable moisture level is 60-70%. This directly affects the drying time of the screed. If this indicator is too low, then the surface of the floor from too fast drying may crack. To prevent this occurrence, the tie should be covered with plastic wrap as soon as it is grabbed. In cases where the moisture level exceeds 70%, an indicator of how much cement screed will dry will be much higher.
Air temperature
The most desirable temperature for drying screeds is 20-25oC. If the room is warmer, the top layer of screed may start cracking. In contrast, lower temperature indices include an increase in drying time. It should be remembered that the microclimate in the room must not be changed throughout the period of reinforcement of cement floors. Any changes, be it sketches, direct sunlight or heating, can cause damage to the coating.
